This performance hit has taken a couple of forms. All quite annoying. App loading time has increased, including the built-in Apple applications. Clicking the messages application to send an SMS takes 7 seconds to load. In the previous version, this was instantaneous.
I’ve also noticed that I am dialing wrong numbers a lot more frequently. I’ve finally figured out why. It seems that my brain was programmed to press the iPhone buttons at a certain rate. With the update in the OS, screen changes happen slower than what I am used to so I’m hitting the wrong contact.
All in all, this is a rather annoying circumstance which after searching the Google machine, I’m not alone in experiencing.
I’m going to try one last thing. Wiping my iPhone and starting with a fresh OS 3.0. If that doesn’t work, I’m going to have to try reverting back to the previous version. A rather disheartening proposition but I’m willing to sacrifice some of the new features for stability and speed.
